A Combination of the Sound Particle Simulation Method and the Radiosity Method

摘要

In room and urban acoustics, ray tracing as well as, for the reverberation tail, radiosity based simulation methods are in use. Any implementation of diffraction into the sound particle simulation method, i.e. a variant of ray tracing, causes a split-up of sound particles and an explosion of computation time. To prevent that, a re-unification effect of sound energies has to be achieved as known from the radiosity method.
